Consolidate YAML files [part-8] (#9347)

* Consolidate YAML files [part-8]

This PR exacts the YAML files referenced from the following subdirs:

- docs/concepts/workloads
- docs/concepts/configuration
- docs/concepts/policy

The following problems are fixed:

- docs/concepts/workloads/controllers/ doesnt have a 'cronjob.yaml for
  test
- the exactly same `pod.yaml` was used in both the task/config-pod-container
  topic and the concepts/configuration topics.

* Update examples_test.go

* Add missing yaml file.
